Definitions

  • the invention relates to a machining center for flat, plate-shaped workpieces. These can consist of wood, chipboard material, plastic, metal or other machinable materials.
  • the plates are clamped in a working plane, whereby the working plane can be arranged horizontally or also vertically.
  • Machining centers of this type are known, and they are generally equipped with drilling and milling tools which can be moved in the parallel plane of the plate-shaped workpieces in the x- and y-axis in CNC program-controllable path curves, arranged on movable tool carriers which can be adjusted by means of mechanical actuators and can be moved into the working position on the workpiece by a mechanically driven or actuated immersion stroke in the direction of the z-axis.
  • the control of the tool and tool carrier movements is effected by a CNC program.
  • the invention also relates to machining centers, in particular for plate-shaped workpieces made of wood, which are equipped with devices for the automatic feeding, positioning, fitting and fastening of fittings, hinges or Like. Additional parts are equipped, and in which the workpiece plates must be positioned and clamped before machining.
  • stop and clamping devices are provided, which consist of stop blocks that can be moved in the x and y axes in the working plane and that can be fixed in the functional positions by adhesive or clamping devices, as well as in the working plane in The x and y axes can be moved as desired, and the workpiece clamping devices can be fixed in the functional positions by means of adhesive or clamping devices.
  • stop blocks and the workpiece clamping devices must be brought into their functional position by hand at the start of the machining run and each time the machining program is changed for another workpiece and fixed there, the workpiece being aligned precisely within the coordinate system at the respective starting point of the machining sequence got to.
  • the object of the invention is derived to provide an embodiment and a mode of operation of the machining center by means of which it is possible to use the stop blocks and the workpiece clamping devices according to a predefined follow-up control program, and without having to spend manual operations in their functional positions and fix them there.
  • a displaceability of the stop blocks and the workpiece clamping devices which can be actuated by means of an additional control program, from their waiting positions or their previously assumed positions into their new functional positions preselected according to the additional control program by influencing the actuators of positioning devices which can be moved as desired in the working plane, and at least one positioning device having at least one driving element, as well as by stop blocks and workpiece clamping devices designed for positive engagement of the driving element. It is provided that the entrainment member can be moved from a rest position into an operative position for positive engagement in a stop block or a workpiece clamping device.
  • the positioning device can be a tool carrier slide or a tool carrier arm. This saves special positioning devices because the tool slide or tool carrier can also perform this task. All that is required for this is that the entrainment member is attached to a tool changing device of the tool carrier slide or tool carrier arm.
  • the tool changing device can be a turret.
  • the driving element has at least one pin or a bolt, and furthermore that the stop blocks and the workpiece clamping devices are provided with elevations or depressions for engaging the driving element.
  • the inventive design of the machining center makes it possible to move the stop blocks for the workpiece plates and the workpiece clamping devices from their respective previous actual positions into their new desired positions, ie functional positions for, in a few seconds to move the next machining runs of a new series of workpieces to be machined.
  • the current ACTUAL positions can be waiting positions at the edges of the working level, or they are the positions that the stop blocks and the clamping devices last assumed during the previous machining process.
  • the stop blocks and the workpiece clamping devices are moved in a matter of seconds from their actual positions into their target positions, ie their functional positions on the working level or clamping level, and precautions must be taken to ensure that they are not inadvertently, e.g. B. deviate from this predetermined position by machine vibrations or other influences. Since such machining centers are designed for extremely high accuracy requirements, even the slightest deviations from the specified positions cannot be permitted.
  • adhesive is provided for feeding and at least until the workpiece is finally clamped onto the stop blocks and workpiece clamping devices, which in a preferred embodiment are arranged on the underside of the stop blocks and workpiece clamping devices facing the working plane . It is preferably provided that the stop blocks and the workpiece clamping devices are provided with holding magnets acting on their underside facing the clamping plane forming the working plane, the holding magnets being permanent magnets.
  • stop blocks can be equipped with vacuum suction heads on their underside facing the clamping plane forming the working plane.
  • vacuum suction heads can be connected to control devices and vacuum pumps in such a way that they can only be subjected to a slight vacuum during their shifting to their functional position and therefore exert a sufficient adhesive force for fixing in their respective position. By switching the suction heads can be loaded with the full vacuum and therefore exert the necessary adhesive force during the processing of a machining sequence.
  • the workpiece clamping devices are equipped on their underside facing the clamping plane forming the working plane and on their upper side with vacuum suction heads.
  • the suction heads arranged on the underside can be subjected to vacuum by means of corresponding control devices in such a way that a lower adhesive force which is sufficient for fixing can be exerted, while the full adhesive force is available by switching over for the processing time.
  • the top and bottom with either vacuum suction heads or with permanent or electric holding magnets.
  • the vacuum suction heads and holding magnets on the upper side of the workpiece clamping devices can be replaced by known mechanical clamping clamping devices, which can also be operated remotely.
  • the machine bed of the machining center is designated by 1 and the clamping plane arranged thereon by 2.
  • the plate-shaped workpiece 3 shown for example has outer contours 4 and inner contours 5, the latter each representing a section of the workpiece plate 3.
  • both stop heads 10 and workpiece clamping devices 20 are on standby at both ends of the clamping plane 2 in waiting positions to be used at any time when changing the workpiece plate 3.
  • the workpiece plate 3 is mounted on the stop blocks 10 and the workpiece clamping devices 20, indicated by dash-dotted lines in FIG. 1, as can also be seen in FIG. 2.
  • the stop blocks 10 are equipped with retractable stop pins 11, against which the workpiece plate 3 is placed.
  • the workpiece clamping devices 20 can according to the exemplary embodiments. 1 to 4 can be equipped with vacuum suction heads or with holding magnets, in particular electromagnets.
  • the supply lines for the energy supply of these adhesives are denoted by 12 and lead to the two ends of the clamping level 2, where they lead to the supply reels 8 via supply deflection rollers 7 and from there are connected in a manner not shown via control devices to the respective energy supply device are.
  • a machining tool (milling cutter) 31 which is fastened in a sleeve 30, can also be seen in FIG. 2.
  • FIG. 4 Another embodiment is shown in FIG. 4, in which the clamping plane 2 of the machining center is arranged vertically.
  • the workpiece clamping devices 20 are recognizably provided with depressions 25 - see FIG. 6 - into which the driving bolts 36 of the driving element 35 engage and can move the workpiece clamping devices 20 in the vertical plane, in which they can be moved by means of adhesive, e.g. B. holding magnets - are held.
  • the tool carrier 6 is equipped with a turret 33, which carries various machining tools 32, and which is also provided with the driving element 35, which is used whenever the positioning of the stop blocks 10 and / or the workpiece clamping devices 20 is changed can.
